Title: Semiconductor pressure sensor and its manufacture
Inventor: TERADA MASAKAZU
IPC: H01L29/84
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor pressure sensor to be manufactured at a low cost while abolishing a glass seating in the constitution of forming a reference pressure chamber in a single-crystal silicon substrate in a sealed state. SOLUTION: After a small opening part 19 is formed at a predetermined location in an insulating film 18 formed on the back surface of an Si substrate 12, an alkali anisotropic etching is performed. As etching speed on a (111) surface is extremely slow in the alkali anisotropic etching, small cavities in a shape surrounding the small opening part 19 along the (111) surface are formed in a connected state, and an edge part appears, and etching the edge part on a (311) surface, small cavities with the (111) surface as a wall surface are formed again. Finally, a cavity 17 corresponding to an envelope surrounding the overall small opening part 19 with the (111) surface is formed, and an Si diaphragm 13 for detecting pressure is formed on the opposite side. Then by sealing the small opening part 19 with a thin film 20, a reference pressure chamber 21 is formed.

Title: Analogue-digital converter
Inventor: TORII KENICHI
IPC: H03M1/14
Filed: 1979-12-27
Abstract: PURPOSE:To obtain a converter where the conversion error due to the error of the input voltage to comparators is small and the conversion speed can be higher, by using comparator groups, the differential amplifier, analogue switch groups, and so on. CONSTITUTION:Input analogue voltage 11 and the first different reference voltages A (taken out from respective connection points between voltage dividing resistances 14-3 and 14-4, between 14-4 and 14-5, and between 14-5 and 14-6) are compared with each other by comparator groups 13-1-13-3. On a basis of this comparison result, one voltage A is selected by analogue switch groups 17-1-17-4. The differential voltage between this voltage A and voltage 11 is amplified by 18. This output is compared with the second different reference voltage B (taken out from respective connection points of voltage dividing resistances 28-1-28-6) at an interval approximately equal to the interval (divided voltage) of voltage A by comparator groups 20-1-20-5. Comparison results of comparator groups 13-1-13-3 and 20-1-20-5 are converted to digital codes by 25. Consequently, since voltage A is fixed and the error of voltage B becomes small, the conversion error is reduced, and the conversion time is shortened, and thus, the conversion speed becomes high.

Abstract: PURPOSE:To eliminate a trouble in the rotation of a stator even with a large heat generation by the operation of a long period or with a high torque by movably engaging a roll between the outer periphery of the stator and the inner periphery of a frame with a spring material. CONSTITUTION:A spring material 53 having a holding function is interposed between a roll 50 and the outer periphery of a rotating stator 12A. The roll 50 is brought into close contact with the inner periphery of a frame 10 by the material 53, and the roll 50 is interposed stably on the outer periphery of the stator 12A by the holding function of a retainer 52 and the material 53. Further, the part of the material 53 has a gap to become the outer periphery of the stator 12A, and the roll 50 is movably engaged with the outer periphery of the stator 12A while being held by the material 53. Thus, it prevents an engaging part from grating or fixing upon thermal expansion of the stator 12A due to the heat generated from the resistance material of a rotor conductor.

IPC: G02F1/136
Filed: 1991-06-17
Abstract: PURPOSE:To form a conductor which is used for anode oxidation and floats electrically and eventually by connecting a 1st conductor to electric conductors between picture elements which are not concerned in the driving of a nonlinear element, and forming an insulator by the anodic oxidation and then disconnecting it. CONSTITUTION:When the anode oxidation of floating parts 63 and 64 is performed and the film of insulators is formed at their end parts for the formation of a nonlinear element, the conductors 34 and 35 between the picture elements serve as common electrodes respectively and the floating parts 63 and 64 are supplied with potentials for the anodic oxidation from the electric conductors 34 and 35 between the picture elements. Namely, the floating part 63 is connected electrically from the adjacent electric conductor 34 between the picture elements through a conductor 73. After the anode oxidation of the floating parts 63 and 64 ends, the conductors 73 and 74 have opening parts 83 and 84 removed without photoetching. The floating part 63 is therefore connected electrically not to a conductor 33, but to the adjacent conductor 34.

Title: Resist coating device
Inventor: OKUMA TORU
IPC: G03F7/16
Filed: 1984-08-17
Abstract: PURPOSE:To prevent a resist from dropping by coating the outer periphery of a nozzle for dropping the resist with the second fine tube, and holding the tube under a reduced pressure to attract the modified substance at the end of the nozzle at the resist dropping time. CONSTITUTION:The periphery of a dropping nozzle 2 is coated by the second fine tube 7. The difference between the outer diameter of the nozzle 2 and the inner diameter of the tube 7 is approx. 1-0.4mm.. The end of the nozzle 2 is retracted approx. 1mm. from the end of the tube 7, and siffuciently coated by the tube 7. The tube 7 is reduced under pressure to approx. 500mm.Hg, and held. According to this construction, modified resist (a) in the nozzle is discharged from the nozzle when dropping to next wafer, but since the discharging pressure is first small, most is attracted to the tube 7 at the end of the nozzle 2 not to drop onto the wafer, and the resist crept to the outer periphery of the nozzle after dropping is finished is immediately attracted to reduce the contamination of the nozzle. Thus, the uniformity of the thickness of the resist film on the wafer can be remarkably improved.

Abstract: PURPOSE:To execute the vehicle induction control of a bus priority system by calculating one bus as (n) vehicles, and bringing blue to an end at the time point when a ratio of passing vehicles in the course of a blue time brought to induction control is maximum. CONSTITUTION:A CPU 1 predicts the efficiency (number of passing vehicles/ display blue time) of passing vehicles in a stop line position, from a sensing pulse sent from a sensor for a general car and a bus installed in the upstream of an intersection, and displays blue until the time point when the effect is maximum. In this case, it is tried to allow the bus to pass through a preferentially by calculating one bus as (n) vehicles, but one bus is expressed in terms of (n) vehicles as to only the latest model bus, and as for the one in the past, it is calculated as one vehicle. In such a way, an appropriate control is executed, and the control adapted to a traffic state is executed.

Title: Steering wheel
Inventor: ONO SATOSHI
IPC: B60R16/02
Filed: 1984-08-21
Abstract: PURPOSE:To prevent a pad section from rattling, by fitting column side and pad side sun gears onto a common boss by means of bearings. CONSTITUTION:When a ring section is rotated in association with the steering operation of a vehicle, a boss 4 and a boss plate 7 are rotated. Then, planetary members 14 supported to the boss plate 7 revolute while they revolve around the outer peripheries of column side and pad side sun gears 9, 12. Meanwhile, the column side and pad side sun gears 9, 12 rotate relative to the boss 4 due to the provision of bearings 8. Since the column side sun gear 9 is unrotatably locked to a column 1 by means of a locking member 10, the pad side sun gear 12 which is relatively rotated by the planetary members 14, does not rotate with respect to the column 1. Accordingly, a pad section 13 is unrotatably fixed to the column.
